JAMES S. BRENNAN, OF ATTLEBORO, MASSACHUSETTS.

RUDDER FOR SAIL OR, OTHER. VESSELS.

To all whom it may concern:

Be it known that I, JAMES S. BRENNAN, a citizen of the United States,residing at Attleboro, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in Rudders forSail or other Vessels, of which the following is a specification.

This invention relates to certain new and useful improvements in ruddersfor sail or other vessels, and the object thereof is to provide a rudderwhich has a pivoted wing, combined with means associated with the rudderwhereby the wing will be quickly moved upon operation of the rudder Afurther object of the invention is to provide a simple, inexpensive andefficient rudder of the type set forth, and one which will readily andquickly respond to the touch of the operator.

In the drawings: Figure 1 is a side elevation of the invention, partlybroken away and in section, and Fig. 2 is a section taken on the line2-2 of Fig. 1.

The rudder post 1 is secured to the stern of the vessel and has theusual operating member 2 secured to its upper end. The rudder 3 issecured to the lower end of the post 1 and has a pint-1e 4 dependingfrom its lower side, which pintle is journaled in a bearing 5 that issecured to the vessel. A wing 6 is pivoted to the front end of therudder 3 at 7, and has a tube 8 rigidly secured to its top side. A rod 9is slidingly mounted in the tube 8 and has an eye 10 formed on its innerend, which eye receives the lower end of a fulcrumed pin 11, the latterbeing provided with a head 12 to pre vent disengagement between the pinand rod 9. The pin 11 may be secured in or journaled in the bearing 13that is supported by the stern of the boat.

In operation, when movement is imparted to the rudder 3 through themedium of the post 1 and operating member 2 the outer end of the wing 6will be given movement about its pivotal connection 7 with the rudder 3,for instance, as depicted in dotted lines in Fig. 2, which movement isthe result of the connection that the wing has with the vessel, namely,the fulcrum pin 11 and the rod 9, the fulcrum pin 11 having a. relativestationary position with respect to the vessel, and the rod 9 havingswinging movements about the fulcrum pin 11, and since the rod 9 isslidingly mounted in the tubular bear- Specification of Letters Patent.

ing 8 it will be seen that when the rudder is moved in either directionlaterally of the vessel, the wing 6 will be given corresponding movementin the same direction, but at an angle to the rudder, which angle isgreater relative to the longitudinal axis of the vessel than the anglewhich the rudder has with the longitudinal axis of the vessel, wherebythe vessel will more quickly respond to the steering movements impartedby the operator to the operating member 2.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In combination with a vessel, a rudder pivotedrelative to the vessel, a vertically disposed wing pivoted to the outerend of the rudder, a tube secured to the top side of the wing, a rodslidingly mounted in the tube and having an eye at its inner end, and avertically disposed fulcrum pin carried by the vessel and receiving theeye of said rod and having a head on its lower end that engages the eye.

2. In combination with a vessel having a pivoted rudder, a wingpivotally connected to the rudder, a vertically disposed fulcrum pincarried by the vessel and terminating in spaced relation to the outertop side edge of the rudder, and means pivoted to the pin and slidablyconnected to the wing so as to move therewith and slide independentlythereof whereby when the rudder is moved said means will move about thepin as a fulcrum and effect movement of the wing about its pivotalpoint.

3. In combination with a pivoted rudder and a wing pivotally connectedto the rudder, a member connected to the wing so as to move therewithand slide independently thereof, and a fulcrum member for connectionwith the vessel having a pivotal connection with said slidable member.

4. In combination with a pivoted rudder and a wing pivotally connectedto the rudder, a fulcrum member for connection with the vessel, andmeans pivoted to the fulcrum member and connected to the wing so as tomove therewith and slide independently thereof whereby when the rudderis moved the said means will move about the fulcrum member and bysliding engagement with the wing move the latter relative to the rudder.

5. In combination with a pivoted rudder and a wing pivotally connectedto the rudder, means connected to the wing so as to move therewith andslide independently thereof to operate same, and means for connectionwith the vessel in pivotal connection with said slidable means toactuate the lat- -f ter and thereby the wing When the rudder is moved.

6. In combination with a pivoted rudder and a Wing pivotally connectedto the rudder, Wing operating means, means to mount said means on thetop edge of the Wing so as to move therewith and slide independentlythereof, and means to pivotally connect the first named means to thevessel disposed adjacent to the outer end of the rudder.

In testimony whereof I have signed my 15 name to this specification inthe presence of two subscribing witnesses.
